Step S712 may continue to step S710 as shown in FIG. 9, or may continue to step S706 as shown in FIG. When the step S706 is continued, the battery monitoring module 400 determines that the battery unit 420 discharges and stops transmitting the battery status information. However, if the maintenance personnel need to obtain multiple battery status information, only the trigger signal Vt needs to be provided to the battery monitoring. Module 400. When the battery monitoring module 400 receives the trigger signal Vt, it begins to transmit the battery status information of the battery unit 420.
